What else can I help you with?
What type of quadrilateral has two 80 degree angles and two 100 degree angles?
It is a parallelogram or a rhombus
What type of triangle if it angles 32 degree 126 degree 32 degree?
Angles have toad to 180 degrees to be triangle so you have no triangle as angles add to 190. If angle is 116 degrees instead of 126 degrees you have isosceles triangle
Is a 200 degree angle an obtuse angle?
No, a 200 degree angle is a reflex angle. Reflex angles are angles that measure more than 180 degrees.
Degree of an angle in a regular octagon?
The sum of angles of a regular polygon in degrees = 180(n - 2), where n is the number of sides of the regular polygon. So, where n = 8 the sum of angles in degree = 180(8 - 2) = 180(6) = 1,080 Angle in degree = (The sum of angles in degree)/n Angle in degree = (1,080)/8 = 135 Thus, in a regular octagon, the degree of an angle is 135.
How many right angles do perpendicular lines make?
Perpendicular lines make four 90 degree angles otherwise known as right angles.
What term is used to describe the shape of a mineral that has three directions of cleavage that intersect at 90 angles?
The term used to describe the shape of a mineral that has three directions of cleavage intersecting at 90-degree angles is "cubic" or "isometric." Minerals that exhibit this type of cleavage typically form cubic crystal systems, such as halite or pyrite. This characteristic cleavage results in the mineral breaking along smooth, flat surfaces that create cube-shaped fragments.
What are two minerals with cleavage?
Halite and Calcite. Halite has what is known as cubiccleavage, where there is cleavage in three directions at 90 degree angles. Calcite has what is known as rhombohedral cleavage, where there is cleavage in three directions but at 120 and 60 degree angles.
What two minerals have cleavage planes at right angles?
haltite breaks easily into distinct sheets. Also Pyroxene is another, it breaks at 90 degree angles in 2 directions.
What is the cleavage for jade?
3 planes at 90 degree angles
What mineral contains sodium and chlorine also breaks at 90 degree angles in three directions?
The mineral you are referring to is halite, commonly known as rock salt. It consists of sodium and chlorine atoms that are arranged in a cubic crystal structure, which causes it to break along 90-degree angles in three directions.
Non silicate contains sodium and chlorine breaks at 90degree angles in three directions?
The mineral described is halite, which is a non-silicate mineral composed of sodium and chlorine atoms. Its crystals typically form in a cubic shape, breaking at 90-degree angles in three directions. Halite is commonly known as rock salt and is often found in sedimentary environments.
What are crystal form and cleavage?
Crystals come in different shapes, determined by how the molecules of compounds from which they are made can be packed together. For instance a quarts crystal is hexagonal in shape, while galena and pyrites crystals are cubic. There are six different crystal shapes or forms determined by the axes and degree of symmetry of the crystal and the angles at which the axes intersect. Subordinate to the overall crystal shapes, many crystalline substances have within them planes of weakness along which the crystal may break these lines are related to the crystals symmetry and caused by how the molecules are aligned within the crystal. This is cleavage.
What angles form square angles?
90 degree angles.90 degree angles.90 degree angles.90 degree angles.
How many planes does calcite have?
Calcite commonly exhibits three notable cleavage planes, which are oriented at approximately 75-degree angles to one another. This characteristic cleavage is a key feature that helps in identifying calcite among other minerals. Additionally, calcite can exhibit a rhombohedral crystal habit due to the arrangement of its atoms. Overall, its cleavage and crystal structure contribute to its unique optical properties.
What supplementary angles have equal degree measure?
2 90 degree (right) angles
Why are all obtuse angles not the same size?
They are not all the same because obtuse angles vary from 90 degree angles to 180 degree angles.
What angles are greater than 90 degree but less than 180 degree?
They are obtuse angles.
